' STEAM-HAMMER.

Specification of Letters Patent.

Patented Oct. 30, 1906.

Application filed May 26, 1905. Serial No. 262 443.

To all iohom it may concern.-

Be it known that I, WILLIAM J. HAGMAN, a citizen of the United States, residing at Philadelphia, Philadelphia county, Pennsylvania, (whose post-oflice address is care Bement, Miles & Company, Philadelphia, Pennsylvania,) have invented certain new and useful Improvements in Steam-Hammers, of which the following is a specification.

This invention, pertaining to improvements in steam-hammers, will be readily understood from the following description, taken in connection with the accompanying drawings, in which-.

Figure 1 is a side elevation of a portion of the frame of a steam-hammer embodying my invention; Fig. 2, a similar view illustrating the modification, and Fig. 3 a horizontal section of the construction illustrated in the 7 other views.

In the drawings, ignoring Fig. -2for the present, 1 indicates the upper portion of the frame of a single-frame steam-hammer of general ordinary construction; 2, the usual top flange thereof for the support of the steam-cylinder; 3, the neck or that portion connecting the cylinder-flange with the general portion of the frame; 4, a pair of guideseats secured against the front of the upper portion of the frame in the general field of the hammer-guides; 5, cross-ties, extending across between the guide-seats at their tops and bases and rigidly formed with them, these cross-ties being disposed so far rearward of the face of the guide-seats as to provide room for the vertical play of the usual hammer, the two guide-seats and their crossbars forming together a rigid integral guideseat structure secured to the face of the frame; 6, bolts firmly uniting the guide-seat structure to the frame; 7, vertical hammerguides secured against the front faces of the guide-seats, the opposing surfaces of these two hammer-guides being adapted to be engaged by and serve in guiding the hammer, as usual, and 8 bolts firmly uniting the hammer-guides to the guide-seats.

The hammer-guides are separably secured to the guide-seat structure, and the guideseat structure is separably secured to the main frame, and these parts may be of similar or dissimilar metals. The guide-seat structure may, if it becomes damaged, be replaced without the necessity for renewing the main frame.

In the construction illustrated in Fig. 1 the cylinder-flange, 2 is carried by the main frame, as is usual in steam-hammer construction, and its relationship and capacities are not modified by reason of the guide-seat construction which has been described; but in Fig. 2, from which figure, by the way, the hammer-guides are omitted, the neck 3 instead of being integrally formed with the main frame is integrally formed with the guide-seat structure, so that not .only the guide-seat structure, but also the cylinderfiange, becomes separable from the main frame and renewable independent of the main frame.

I claim as my invention In a steam-hammer, the combination of a main frame having two outwardly-presenting faces in line with each other, a guide-seat structure secured to said faces of the main frame comprising two vertical portions having outwardly-presenting faces, and having cross-ties connecting the vertical portions, and hammer-guides secured to the guideseats having faces corresponding to the guide-seat faces, and provided with hammerguideways opposite each other and at right angles to the faces connecting the hammerseat structure and the hammer-guides.

WILLIAM J. I-IAGMAN.
